Otaku Engineer in Great Tang Dynasty

"Excuse me~!"

When Li Zexuan heard Mo Huai's affirmative words, he couldn't help but breathe a sigh of relief, and at the same time he couldn't help but be shocked. Since Mo Huai said this, doesn't it prove that in this era, someone really started to realize what the universe is, this... This makes Li Zexuan feel incredible~!

"The second question, what is power~?"

Li Zexuan was shocked, how could Mo Huai not be shocked~? Regarding the definition of the universe, he saw it from Mozi’s handwritten notes. He thought that this question alone would make Li Zexuan retreat. Unexpectedly, Li Zexuan, the little doll of the 14th Five-Year Plan, could actually complete the Jedi. Anti-kill, which made Mo Huai very puzzled. After thinking for a while, Mo Huai asked the second question.

"Power~? Is it the power of strength~?"

Li Zexuan suspected that he had heard it wrong, and asked uncertainly.

Mo Huai nodded and said, "Yeah~!"

Li Zexuan smiled, and he opened his mouth and replied: "Force is the interaction between several objects. Interaction means that the motion of an object will change due to the existence of other objects, and an object has only two attributes-mass and speed, so Force can change the motion state of an object. If the speed of an object's increase is defined by acceleration, then the greater the force on the same object, the greater its acceleration..."

Li Zexuan unceasingly converted all the knowledge about force in the later "Physics" book into words that the ancients could understand. Li Gang heard it in the clouds and mists beside him. I don’t know what kind of ghost Li Zexuan was talking about. Huai's pupils shrank and he stared at Li Zexuan with an extremely solemn expression. At this moment, his heart felt as if he had experienced a violent storm, and it was difficult to calm down for a long time.

Mozi, the ancestor of the Mohist school, once gave a detailed definition of "force" in the "Mojing", saying: "Force, punishment (form) is also the reason for fighting." In other words, force is the reason for the movement of objects. The effect of body motion is called force. In this regard, he gave an example to illustrate, saying that it is like lifting a heavy object from the bottom to the top, which can only be done because of a powerful effect. At the same time, Mo Zi pointed out that when an object receives a force, it also produces a reaction force. For example, after two objects of equal mass collide, the two objects will move in opposite directions. If the masses of the two objects differ greatly, the object with greater mass will not move after the collision, but the reaction force will still exist.

Then, Mozi gave the definition of "movement" and "stop". He believes that "movement" is due to force pushing, and "stop" is the end of the motion state of the object after a certain period of time. Although Mo Zi did not clearly point out that the end of the state of motion was due to resistance, he had realized that after the external force disappeared, the state of motion of an object could not exist forever.

To some extent, Mozi's research in the field of physical mechanics is absolutely ahead of the entire world for more than two thousand years~! If Mohism could replace Confucianism as orthodox in the past, then China is likely to become the origin and prosperity of world physics~!

After talking for a full quarter of an hour, Li Zexuan finally stopped. Mo Zhong and Mo Yun, the two young men, looked at Li Zexuan with no contempt. They, as the core disciples of the Mo family, have regard to Mo Zi’s notes and writings. Of course they have a certain understanding, but they spend most of their time learning martial arts. In contrast, their knowledge reserves in this area are far inferior to Li Zexuan~!

They couldn't fight by force, and they were even more incomparable in their knowledge. This made Mo Zhong and Mo Yun, who had always claimed to be the sons of hermits, very hurt~!

Mo Huai closed his eyes and digested the words Li Zexuan just said in his heart, trying to find some loopholes in it, but after a long while, he opened his eyes somewhat disappointed, because he found that what Li Zexuan just said was not only impeccable, but also It was more detailed than the Mohist classics, and even further elaborated and proved some aspects. He hadn't heard of some concepts himself, but he also had to admit that Li Zexuan's words were very reasonable.

"This question, Li County man, you got it right~!"

Mo Huai looked at Li Zexuan with a complex expression, and said.

Although there are rare copies of "Mojing" circulated around the world, in the context of Confucianism, how many people in the whole world will look through this kind of partial book~? Moreover, the theories mentioned by Li Zexuan are obviously beyond the definition of force in the "Mojing". Based on Mozi, he has expanded force into a complete and detailed knowledge~!

Where did Li Zexuan's knowledge come from~? Why does he know so many things~? There are many questions buried in Mo Huai's heart, but it is obviously not the time to ask questions, so he can only endure it.

Li Zexuan smiled slightly. Now he really "likes" the Mohist giant in front of him ~www.ltnovel.com~ more and more. Where can I find such an advanced physics teacher~! Li Gang was a big help this time~!

Li Gang, the party involved, is now stunned~! He wanted to ask Mo Huai, why is this the right answer~? He didn't understand much at all just now~!

Mo Huai took two steps on the spot with his hands, and then he suddenly flashed his inspiration, turned and asked Li Zexuan: "Question three, open flame candles, and put a small hole afterwards, what is happening behind the small hole~? "

Having said that, he fixed his gaze at Li Zexuan. Although he knew the answer from the Mohist classics, he only knew that he didn't know why. He planned to embarrass Li Zexuan later.

Li Zexuan's eyes widened. He now doubts whether this Mo Huai is a traverser. He even knows the image of a small hole~? This is going to heaven~!

"What~? Li Xian male can't answer~?"

Mo Zhong asked happily when he saw this.

Li Zexuan's shock was silent, but in Mo Zhong's eyes he couldn't answer.

Li Zexuan regained his senses, suppressed the shock in his heart, and then smiled: "How difficult is this~! There will be a candle flame upside down statue behind the small hole, and with the small hole in the middle moving back and forth, the size of the image will also vary. It has changed. Giant, what the Lord said is wrong~?"

As a modern engineering student, although Li Zexuan easily answered Mo Huai’s question, he also had the same doubts in his heart as Mo Huai, because small hole imaging involves knowledge of geometric optics. People in the Tang Dynasty How can I know~?

He didn't know that Mo Huai only learned this knowledge from Mohist classics, and the real proponent of Xiaokong Imaging was Mozi! Mozi not only studied mechanics, but also had profound attainments in geometric optics.
